Application November 7, 1933, Serial No. 696,932 3 Claims.v (Cl. 10.290) rThis invention relates to a pump of the type adapted to be loweredinto a well casing or other restricted place and has for its principalobject the provision of a pump of this character which will lift amaximum amount of duid with a minimum amount of power.

Another object of the invention is to so construct the pump that theline of flow of the fluid therethrough will follow gradual curved linesso lo that the water will not be required toA turn sharp ineiicientbends, and in which the rising water will follow a spiral or inclinedpath so that the pump will not be required to lift the water directlyvertical.

A still further object is to provide a pump oi this character in whichthe surface of the irnpeller will be relieved from all back pressure ordead weight of the water column.

Other objects and advantages reside in the detail construction of theinvention, which is designed for simplicity, economy, and efficiency.These will become more apparent fromthe following description.

in the following detailed description of the invention reference is hadto the accompanying drawings which form a part hereof. Like numeralsrefer to like parts in all views of the drawings and throughout thedescription.

In the drawings:

Fig. 1 illustrates a Vertical section through a typical well casingillustrating the pump in place therein.

Fig. 2 is an enlarged section through the pumping portion of the device.

Fig. 3 is a bottom face view of the impeller.

Fig. 4 is a cross section through the pump housing taken on the line 44, Fig. 2.

Fig. 5 is a similar section taken on the line 5 5, Fig. 2.

Fig. 6 is a similar section taken on the line 6 6, Fig. 2, lookingupwardly.

Fig. 7 is a diagrammatic, developed section through the deflectingportion of the pump.

1n the drawings, a typical well casing for receiving the pump isindicated at 10. The pump is supported therein on the lower extremity ofa discharge pipe 11 of the necessary length. The Various lengths of thepump pipe 11 are connected by means of suitable bolt flanges 12. B-e- 50tween the lengths of pipe are shaft bearing members 13, clamped in placeby means of the flanges l2. These bearing members form journals for avertical pump Shaft 14 which extends concentrically throughout thelength of the pipe 11.

In the type of pump illustrated, a belt pulley 15 is secured on theshaft 14 .so that the latter 'l' ley to be iilled with oil throughasuitable oiler 17. The oil from the oil reservoir ldconstantly feeds tosuitable thrust bearings within the pulley 15, which in turn support theweight of the shaft 14. An outlet casting 18 supports the bearings inthe pulley 15 from the pipe 11. The outlet casting is provided with anoutlet 19 through which the water or other iiuidibeing pumpeddischarges.

A pump housing 2() is secured on the lower extremity of'the pipe 11 anda rotor housing 21 is secured upon the bottom of the pump housing 20.The rotor housing 21 is iianged as shown at 22 so that additional pumphousings or additional intake pipe may be secured thereto. f

A semi-spherical rotor 23 is secured upon the bottom of the shaft 14immediately below the pump housing 20 and within the rotor housing 21.The rotor 23 is formed with a convex back plate which when in place isdirected downwardly, as shown in Fig. 2. Upon the convex surface of theback plate is a series of spiral, twisted vanes 24. The vanes 24 curveinwardly toward the axis in a spiral-like direction and simultaneouslytwist in a lateral direction. A line extending laterally across a vaneadjacent the axis will be vertical, while adjacent the periphery asimilarly placed line would be horizontal.

The inner face of the rotor housing 21 ts snugly to the outer edges ofthe vanes 24. The curvature of the Varies is such that their rst impactwith the water, adjacent the axis, would act to direct the wat-eroutwardly and their last impact with the water, adjacent the periphery,would act to direct the water upwardly.

A deflecting member 25 is formed in the pump housing 20 immediatelyabove the rotor 23. It is desired to call particular attention to thedeflecting portion as it forms one of the principal features of theimproved pump. It might be cast integrally with the pump housing 20, asillustrated, or may be a separate section bolted or otherwise securedthereto. In it a series of peculiarly shaped passages 26 are formed.Three passages 26 have been found to be very satisfactory although, ofcourse, the invention is not limited to this particular number ofpassages.

The passages 26 open at the bottom in narrow curved openings 27extending abo-ut the periphery of the rotor, each having a length ofapproximately 120. The passages shorten in length as they pass upwardlyand increase in width so as to open at the top deflecting portion 25 inround discharge openings 28. The passages 26 are inclined both in thedirection of rotation of the rotor 23 and also inwardly toward the axisthereof so that they tend to incline in a general spiral-like direction.Above the deflecting portion 25 is a series of scoop-like shields 29,there being one shield placed on the forward' side of each of thedischarge openings 28 so as to still further direct the dischargingcurrents in a spiral direction as they emerge from vthe pump housing 20.

'Ihe deiiecting portion 25 serves a double purpose; rst, it prevents theweight or pressure of the water column in the pipe l1 from resting orpressing upon the upper face of the rotor 23; second, it causes thewater to pass upwardly on inclined paths which can of course beaccomplished with less power thanI by forcing the Water immediatelyupward. This provides a pump structure which will operate on less powerand deliver more fluid than the usual types of pumps. 1 y

It is readily apparent that additional pumping elements can be securedalong the pump shaft one below the other if desired so as to recreate amulti-'stage effect where high delivery against high pressures is.desired.

- While a specific forrn of the improvement has been described andillustrated herein, it is desired to be understood that the same may bevaried, within the scope of the appended claims, without departing fromthe spirit of the invention.

Having thus described the invention, what is claimed and desired securedby Letters Patent 1. A pump comprising: a vertical shaft; a rotormounted on said shaft, the lower face of said rotor being convex; spiralblades extending from said convex face; a rotor housing surrounding saidrotor in close proximity to said blades; a

dispersion member positioned above said rotor and provided with a seriesof passages for receiving the discharge from said blades, said passagesfollowing substantially spiral lines through said dispersion member; aconical pump housing extending above said dispersion member; anddeflecting flanges extending above the discharges of said passages intosaid pump housing so as to direct the discharging water on an inoline.

2. A pump comprising: a conical pump housing open at its top; a deectingmember positioned in the bottom of said pump housing, there beingpassages extending through said deecting member, said passages havingrelatively long curvated openings in the bottom and substantially roundopenings at their top, the portions of the passages between the bottomand the top being inclined in a spiral; a rotor housing secured to saidpump housing below said deflecting member; and a rotor mounted in saidrotor housing so as to force uid into said passages.
